Mrs. Frisby (The Rats of NIMH)

Now this is something different.
I always thought "How would be like Mrs. Brisby (or Mrs. Frisby) from the original book, 'The Rats of NIMH'?".
I must first state that I made this drawing without reading the book. I know there was a book before Don Bluth made his movie adaptation, but I still hadn't the chance to read it (yet).
So his is my first houht of how would Mrs. Frisby look like, different from Don Bluth's style. More natural and feral, but keeping her old red cloak.

This, again, is my first attempt on drawing her on my style. I shall redraw her in the future, trying new stuff or I shall even read the book to draw her as close as possible to her personality and characteristics.
